Mithril

Cave mining

Mithril is a PC game about exploring and mining in procedural caves. You dig deeper by placing struts to support the ceiling, which can otherwise fall. The caves are generated procedurally, so each new cave brings different dangers.

Ore and lava

You build automation chains to process the ores you mine. You can also manipulate lava, then trigger Dormancy to crystallize new ore in places where lava once flowed. After that, the world remains the same, but you enter a new cave with new dangers.
